Description

Technical Field

[0001] The utility model relates to a plug, in particular to a special plug for spraying paint on a protective shell of a new energy battery. Background Art

[0002] New energy batteries are generally placed in a sturdy aluminum alloy protective shell. During the production process of the protective shell of the new energy battery, it is necessary to spray epoxy resin graphite and other waterproof and anti-corrosion materials on its surface. Since the protective shell of the new energy battery is provided with multiple holes for the subsequent installation of wires, the above holes must be reliably covered before the waterproof material is sprayed in to prevent the waterproof material from entering the holes and the inside of the protective shell. The existing processing method is to first stick the holes of the new energy protective shell with a specially shaped sticker, wait for the spraying to be completed, and then tear it off manually. However, since the surface of the protective shell is completely covered with epoxy resin graphite at this time, the worker needs to use a knife to rely on experience to mark the edge of the sticker, and then tear off the sticker by hand. The above steps are highly dependent on the experience of the workers, and the sticker has a strong adhesion to the protective shell after heating, which makes it difficult for the workers to operate and the environment is harsh.

[0003] In order to solve the defects of the prior art, the utility model provides a special plug for spraying paint of a new energy battery protective shell, which can cover the holes of the protective shell to ensure that the corresponding holes remain clean during the painting process, is easy to disassemble and assemble, and can be recycled.

[0004] In order to solve the above technical problems, the utility model provides a special plug for painting a new energy battery protective shell, including a plug body, a material removal rod and a limiting marble. The plug body includes a clamping portion that matches the shape of the corresponding opening of the new energy battery protective shell, and a top cover that is located on the surface of the clamping portion and extends evenly outward from the edge of the clamping portion. The material removal rod is arranged on the front side of the top cover; the limiting marble is arranged on the side of the clamping portion and extends outward relative to the side of the clamping portion. A spring is arranged between the bottom of the limiting marble and the clamping portion.

[0008] As an improvement of the above solution, a protective ring is further included, and the protective ring covers the side surface and the bottom surface of the top cover.

[0009] As an improvement of the above solution, the top cover is circular, elliptical, quadrilateral or triangular.

[0010] As an improvement of the above solution, there is a gap between the protective ring and the top cover.

[0011] The implementation of this utility model has the following beneficial effects:

[0012] With this embodiment, before spraying the anti-corrosion paint, you only need to select the corresponding plug according to the shape of each hole in the protective shell, and insert its snap-fitting part into the corresponding hole. When the snap-fitting part is snapped into place, the limit marble will just pass over the shell of the protective shell and reach the inside of the protective shell. The limit marble will pop out, and the plug will be fixed in the hole with the top cover, which is convenient for installation. When the painting is completed, the material extraction rod will remain extended outward. At this time, the material extraction rod can be clamped manually or by a special machine to pull the plug out of the hole, which is convenient for disassembly. After the disassembled plug, the epoxy resin graphite attached to the surface is removed with an organic solvent such as thinner, and it can be reused after drying, which is energy-saving and environmentally friendly.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0019] like Figure 1 and Figure 2As shown, the first embodiment of the utility model provides a special plug for spraying paint of a new energy battery protective shell, including a plug body 1, a material taking rod 2 and a limiting marble 3. The plug body 1 includes a clamping part 11 matching the shape of the corresponding opening of the new energy battery protective shell, and a top cover 12 formed by uniformly extending outward from the edge of the clamping part 11 on the surface of the clamping part 11, and the material taking rod 2 is arranged on the front of the top cover 12; the limiting marble 3 is arranged on the side of the clamping part 11 and extends outward relative to the side of the clamping part 11, and a spring 4 is arranged between the bottom of the limiting marble 3 and the clamping part 11. Among them, the shape of the top cover 12 matches the shape of the corresponding hole, and according to needs, the shape of the top cover 12 can be circular, elliptical, quadrilateral or triangular.

[0020] With this embodiment, before spraying the anti-corrosion paint, it is only necessary to select the corresponding plug according to the shape of each hole in the protective shell, and insert its snap-fitting part 11 into the corresponding hole. When the snap-fitting part 11 is snapped into place, the limit marble 3 will just pass over the shell of the protective shell and reach the inside of the protective shell. The limit marble 3 pops out, and cooperates with the top cover 12 to fix the plug in the hole, which is convenient for installation. When the painting is completed, the material extraction rod 2 will remain extended outward. At this time, the material extraction rod 2 can be clamped manually or by a special machine to pull the plug out of the hole, which is convenient for disassembly. The disassembled plug uses an organic solvent such as thinner to remove the epoxy resin graphite attached to the surface, and can be reused after drying, which is energy-saving and environmentally friendly.

[0021] Preferably, combined Figure 3 and Figure 4 According to the second embodiment of the utility model, in order to speed up the installation speed of the plug and reduce the installation requirements, the two sides of the clamping part 11 are provided with avoidance parts 13, and the surface of the avoidance parts 13 is an arc surface. By providing the avoidance parts 13, the contact surface between the clamping part 11 and the inner wall of the hole can be reduced, thereby reducing the difficulty of installing the plug. The surface of the avoidance part 13 is an arc surface, which can reduce the possibility of interference between the clamping part 11 and the internal structure of the protective shell, improve the adaptability of the plug, and increase the applicable occasions of the plug.

[0022] Preferably, the front of the top cover 12 is provided with a horizontal positioning groove 121 extending to the edges on both sides. The horizontal positioning groove 121 is a linear groove. By setting the horizontal positioning groove 121, the rotation angle of the plug can be determined. For some holes with angle requirements, the horizontal positioning groove 121 can be used in conjunction with a level ruler to ensure the installation accuracy of the plug.

[0023] In order to facilitate gripping, a blocking block 21 is provided at the end of the material picking rod 2 . The blocking block 21 is disc-shaped, and the diameter of the blocking block 21 is larger than the diameter of the material picking rod 2 .

[0024] Combination Figure 5As shown, according to the third embodiment of the utility model, the difference from the first and second embodiments is that it also includes a protective ring 5, and the protective ring 5 covers the side and bottom surfaces of the top cover 12. Cleaning the plug after each use will greatly increase the production cost. Therefore, in this embodiment, the side and back of the top cover 12 are provided with protective rings 5, and the protective rings 5 ​​are directly inserted into the top cover 12 from one side of the clamping portion 11. By adding the protective rings 5, the protective rings 5 ​​can be removed, replaced and cleaned separately after each use, thereby ensuring that the bottom surface of the top cover 12 in contact with the corresponding hole of the protective shell is kept clean. The plug can be cleaned after being used several times, further improving production efficiency and reducing production losses.

[0025] More preferably, there is a gap between the protective ring 5 and the top cover 12, so that the protective ring 5 can be easily removed from the top cover 12, making disassembly and assembly convenient.

[0026] The above is a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present utility model.
